In duncantl/CodeAnalysis: Tools for Static Analysis of R code

In topics.md, this corresponds to Refactoring functions to smaller, more modular functions. Detect blocks of expressions that have direct data dependence and make these into functions.

The idea is that we have a function that really consists of two or more separate tasks and then combines the results from these two to return the result

function(...)
{
   # expressions for task 1

   a = 
   b = 
   c = 

   # expressions for task 2

   x = 
   y = 
   z = 

   foo(c, z)
}

We could rewrite this as

function(....)
{
     c = task1()
     z = task2()

     foo(c, z)
}

This makes the code clearer, more reusable and we can test the two functions task1 separately and easily provide alternative implementation for either.
